The stock head has way too much flow for the power it's making. Air speed is really bad too. Comparing to some other N/A heads, its making as much flow as ones that do 260bhp so the fact it doesn't make that is down to the combination of other parts.
I've yet to touch the intake manifold and my feeling is that a problem area. Logging what I do in the ecu I can see several issues going on. When i fix them i'll post up details. Just short of time for the project right now.

Just to confirm, was the dyno on the stock exhaust manifold aswell?
I've been noticing some of your posts around the boards, I'm really excited by what you've been doing.
